The Why Behind the Numbers
Understanding the basics makes results stick.
What are calories?
Calories are the energy your body uses to live, move, and recover. Eating in the right range is what drives whether you lose, maintain, or gain weight.
Why protein matters
Protein preserves muscle while you lose fat, fuels recovery, and keeps you fuller longer. It's the most important macro to hit consistently.
Why steps matter
Daily steps burn 2–3× more calories than your workouts. They're the quiet, sustainable engine behind fat loss — no extra recovery required.
Why sleep affects fat loss
Poor sleep raises cortisol, increases cravings, and lowers your willpower. 7–9 hours protects your hormones and your progress.
